A sociolinguistic survey conducted and summarized by AMy Kim and Seung Kim under the aegis of SIL International. This report presents the findings of a survey conducted in the Bishnupriya community of Bangladesh in March 2003. Data gathered through word lists, sociolinguistic questionnaires, and SRTs are presented and analyzed to determine the current sociolinguistic situation. In brief, it was concluded that the Bishnupriya are highly bilingual in Bangla, the national language, but also speak their mother tongue enough to keep its vitality high and have a positive attitude towards their mother tongue. Still, an increased use of mother tongue literacy would strengthen its usefulness and vitality even more.
